Letters Patent No. 99,422, dated February 1, 187 0,

a IMPROVEMENT IN' JOURNAL-BOXES.

f The Schedule referred to inthese Letters Patent anti making part cfthe same.

To all whom it may concern Be it known that I, SETH C. ELLIS, of JerseyCity, in the county of Hudson, andfState of New Jersey, have invented anew and useful Improvement in Journal-Boxes, oi' whih the following is afull, clear, and exact description, reference being had to theaccompanying drawing, forming part of this specification, and in which-Figure l represents a vertical section, taken transversely through theshaft of a journal-box, constructed in accordance with my improvement,and as applied to the. shaft; l

Figure 2, a, similar view of va modification of the same; and

Figures 3 and 4, plans thereof. 4 Similar letters of reference indicatecorresponding parts. My improvement consists in a ilove] connection ofthe cap or gland with the base portion of the journalbox, whereby, undera horizontal arrangement of the base, said cap is made to bear down uponthe shaft, or is restrained from lift, by its weight acting incombination with friction, through a guiding-action o'r bearing, it ismade to have, on or against the baseportion, under control of' aholding-screw, arranged to occupy a tangential relation to the shaft, sothat in tightening up, said screw exerts no force to press the cap downupon the bearing, but, on slackening, allows of the cap falling toadjust itself to the bearing. By this improvement, a seltadjnstingcharacter is given to the journal-box, and an easy or gentle bearing ofthe cap down upon or against the shaft, free from any binding-action bythe holding-screw, is secured.

Referring, in the tirst instance, to gs. l and 3 of the drawing- Y Arepresents the base or fixed portion of the jonrnal-box, the base orgronndsurtace of which will here be assumed to occupy a horizontalposition.

B is the shaft; and

C, the movable portion, cap, or gland of the box.

The hase-portion A oi the box is formed with an upright arm or side, a,having a vertically oblong slot, b, through it, and the movableportionor cap C conp structed with a similar arm or side, c, which fitsor bears against the inner face of the fixed arm a, so that the latteracts as a friction or bearing and guiding-suri'ace-to the cap (l, ou itsbeing slid toward or from the shaft B, and also operates as a.holding-sur face for the cap, when secured to the base-portion by ascrew-bolt, D, arranged to pass, in tangential relation tothe shaft,through Vthe arm c of the cap, and.

slot b of the arm a. of the fixe-d portion of the box.

On slackening this bolt D, or nut on the end of it,

the cap'O is free to adjust itself to the shaft B, and

its weight, in combination with its friction'al bearing against the arma, restrains it frombeing lifted, when only slightly secured by thescrew-bolt D, so that said cap has a self-adjusting and gentle, yetclose bearing secured to it on the shaft, and no further tightening ot'the screw-bolt will cause it to bind or bear unduly hard theron. lhusthere is no particularity necessary as regards the adjustment of theholding-screw, to secure' a perfectthat is, neither too hard nor tooloose- 't of the cap to the. shaft, as occurs in the ordinary In certaincases, two caps or glands, arranged todiverge from each other, and madeto bear or rest on inclined upper surfaces formed in or on upperextension of the base-portion ofthe box, may be used, the arms or sidesof said caps being slotted, for insertion of the holding-screws throughthem, to secure a like action of the cap or gland, as hereinbeforedescribed, although 'there may be employed, in addition, it' desired,adjusting-screws at top of the base-portion, to facilitate the settingdown of the cap on the holdingscrews, which secure the caps to thebase-portion, being sniiciently slackened for the purpose.

hat is here claimed, and desired to be secured by Letters Patent, is`

The holding-screw D, arranged in a position tangential to the shaft, i`ncombination with the sliding or self-adjusting cap C and stationaryportion A of the box, substantially as specified.
